Noah, you can't use that argument. Perhaps a better number to look
at would be how many ASN's there are in the routing table, and how
many of them are IPv4 only vs how many have both IPv4 and IPv6 or
even IPv6 only.<br>
<br>
Most ISP's run with one ASN but many run with multiple ASN's - but I
believe ASN's would be a better measurement.<br>
<br>
I, as an ISP advertise one /32 of IPv6, and multiple IPv4 prefixes.<br>

<div>In fact, I would argue that by insisting on holding
resources in the free pool for “possible future
newcomers” you are, in effect, assigning them to
organizations without any current proof of physical
infrastructure in the AfriNIC service region to the
disadvantage of organizations that do currently have
proof of infrastructure and a documented need for the
addresses within the region today.</div>

Occasionally at AFRINIC Meetings, we have an "IPv6 only" day.
Generally, most people survive just fine. I think this "IPv6 Only"
day event should perhaps be something we always do at our meetings.
Its also been done at SAFNOG (Southern African NOG) a few times.<br>
